Peter, I’m not completely sure because I have my amp in the shack within reach, but I think you’ll need to switch in and out of standby from the amp itself (unless you’re using remote software) …. But regarding the second question, if you have selected “power per band” from the K3s menu, and if you have the rig and KPA1500 connected with the auxiliary cable, the K3s power settings will follow the oper/stby selection on the amplifier…. And will be specific for each band. When you switch into standby, the K3s will switch to the barefoot power of your choice (100W in your case) …. When you switch to operate, the K3s will drop to the drive power that had been selected the last time you used the amplifier on that band.

I do have two questions, however. First, is it possible to toggle standby and operate from the K3s, instead of using either the remote software or physically pressing the button on the amp? And second, I was under the impression that there was a way to have separate transmitter powers depending on whether the amp is inline or not. I normally like to run the full 100W from the K3s, but when I kick the amp in, I have to drop TX power to ~25 Watts. Another issue I have involves the feed path. I am using a remote antenna switch mounted at the tower. At the moment I have all my HF antennas connected through there, using the Antenna 1 port on the amp (previously on the K3s). Antenna 2 is for 6m only. I would like to route the 6m antenna from this switchbox as well, but the problem is the HF output is running through a low-pass filter. Are there low-pass filters that don't cut off until ~54 MHz? ---------------------------------------------------- Regards, Peter Dougherty ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
